Title: Process for producing oriented short-fibre fleeces
Inventor: SIEGLING HANS FRIEDRICH CHEM I
IPC: D21F13/04
Filed: 1981-02-03
Abstract: A process for producing fleeces composed of unidirectional short fibres for composite materials is proposed. In this, a fibre suspension is supplied to a vessel, in which a container having a porous circumferential wall rotates. The fibres settle on the porous circumferential wall of the container, whilst the suspension liquid flows into the interior of the container by means of a pressure drop, whereupon the short-fibre fleece formed is removed from the drum. The container having the porous circumferential wall is immersed completely in the suspension, with the result that the settling rate of the short fibres and therefore the fleece-forming rate are increased and it is possible to use a suspension of very high viscosity, for example consisting of a synthetic-resin solution, such as is necessary for the production of "prepregs".

Patent DE-3119568-A1 (DE)
Title: Eccentric worm screw pump
Inventor: BURGER WENDELIN
IPC: F04C2/107
Filed: 1981-05-16
Abstract: The invention is based on an eccentric worm screw pump having a helical rotor (3) which rotates in a stator (1) which has a likewise helical elongated cavity (2) and consists of elastic material and is inserted into a casing (6). According to the invention, the improvement of an eccentric worm screw pump of this type is characterised in that there is situated, in the zone between the rotor (3) and the casing (6), at least one pressure chamber (8) which acts on the elastic stator (1) so as to deform it and is in effective communication with a supply (10) for a pressure medium. The deforming pressure action, taking place via the pressure chambers, on the stator (1) provides for a constant engagement of the mutual contact surfaces of stator (1) and rotor (3). Any leaks arising upon wear of the contact surfaces are automatically compensated for by deformation of the stator (1) in that zone. Thus, constant delivery is still possible even after prolonged use of the eccentric worm screw pump, as a result of which optimum efficiency is likewise maintained during the operating time and the operational reliability of the pump is increased. Expediency and inventive features are characterised most clearly by Figure 1. <IMAGE>

Title: Method for multiplex operation of a liquid crystal display
Inventor: TAUER KARL M DIPL ING
IPC: G09G3/36
Filed: 1981-09-18
Abstract: It is necessary in liquid crystal displays with multiplex operation for the voltages to be precisely observed. The supply voltage is mostly supplied from a battery, so that it is necessary to match the supply voltage to the battery voltage. This matching is achieved digitally and without loss by following each imaging period (tB) with a pause (tV) the length of which is dimensioned so that the root-mean-square value of the voltage characterising the "on" state is equal to the supply voltage of the liquid crystal cell. <IMAGE>

Patent DE-3200644-A1 (DE)
Title: Conical ring elements and units through which fluid flows
Inventor: EICKMANN KARL
IPC: F16J3/02
Filed: 1982-01-12
Abstract: Conventional cup springs require centring guides if a plurality of springs are placed in series. The invention dispenses with guides of this kind since they are formed integrally as self-centring seats on the conical parts of the cups. Tests have shown that elements of this kind with a conical ring stage can also be used to provide new types of unit through which fluid flows. Accordingly, use is made of ring elements containing conical parts in order to form a working chamber through which fluid flows and which can be used, in particular, as a pumping chamber or motor chamber, within the conical part and, if required, also in the middle of the ring. The chamber is assigned inlet means and outlet means and a drive arrangement for compressing and relieving the conical part of the element is furthermore provided. It is possible to have the drive arrangement run under lubricant and to provide it with hydrostatic bearings, while the chamber can also be operated with non-lubricating fluids such as, for example, water or gas. In tests so far pressures of over one thousand bar have been achieved in the working chamber with good efficiencies. It is assumed that it might also be possible on the basis of the invention to operate internal combustion engines at higher pressures or with better efficiencies.

Patent DE-3221142-A1 (DE)
Inventor: GERHAHER MAX DIPL ING
IPC: E04D1/30
Filed: 1982-06-04
Abstract: This invention relates to a ridge tile which defines a ventilating gap between the outside surface of that end portion of the tile which is overlapped in the roof and the inside surface of the overlapping end portion of the adjacent ridge tile in that its end portion which is overlapped in the roof has a flat surface and the lower portions of the outside surface of its overlapped end portion define a clearance with the inside surface of the overlapping end portion of the adjacent ridge tile. It is an object of the invention to provide a ventilating ridge tile which is of the kind defined first hereinbefore and together with an adjacent ventilating ridge tile of the same kind defines a larger effective ventilating cross-sectional area whereas the external size and shape of the ventilating ridge tile are substantially preserved and the universal usability of the ventilating ridge time in a mortar bed or with unbonded joints on roof pane tiles or ridge-adjoining tiles is obstructed or reduced. This is accomplished in that the overlapped end portion of the ridge tile is provided with additional, outwardly sloping, flat surfaces between the surface at the apex of the tile and those portions which define a clearance with the adjacent ridge tile.

Title: Screw-in heating element having one or more tubular heating elements
Inventor: HOEHL HANS-PETER
IPC: H05B3/04
Filed: 1982-06-23
Abstract: The invention relates to a screw-in heating element having one or more tubular heating elements, in which the ends of the tubular heating elements are fixed in a nipple which is provided with an external thread, in an electrically insulating and sealed manner. The invention creates a screw-in heating element which, when used in a storage container having cathodic corrosion protection, does not lead to rapid erosion of the magnesium electrode and itself is protected against premature destruction of its tubular heating elements. This is achieved in that all the tubular heating elements are connected to the nipple in an electrically conductive manner via an electrical resistor network whose resistance value is or can be predetermined, either directly or indirectly via a part which is electrically conductively connected to the nipple.

Title: Device for starting and stopping an internal combustion engine
Inventor: LOEWL WOLFGANG DIPL ING
IPC: F02D37/02
Filed: 1982-06-25
Abstract: The invention proposes a device for starting and stopping an internal combustion engine provided with a starter motor in a vehicle as a function of input switching signals and/or threshold values of input signals, this device being designed as a microcomputer (10). The microcomputer is assigned a detector (25) for error signals, which checks the input signal flanks in such a way that, if at least one input signal flank fails to occur before a starting or stopping command, control output stages (21, 22, 24) controlled by the microcomputer are blocked. In this way, a malfunction of the device as a whole, that is to say unwanted switching off of the internal combustion engine or unwanted actuation of the starter motor (20), is prevented in an effective manner. <IMAGE>

Title: Apparatus for level measurement of liquids in containers, especially level measurement for motor vehicles
Inventor: SIEBENEIKER GUENTER
IPC: G01F23/292
Filed: 1982-11-26
Abstract: In an apparatus for the level measurement of liquids in containers or the like, a sensor element which dips into the liquid and responds to a change of the liquid is used, and also an indicator element which can be controlled by this sensor element and indicates the detected liquid level. For a trouble-free and particularly inexpensive construction of the apparatus, it is proposed to use as the sensor element a radiation conductor which has at least one boundary surface towards the liquid at the desired height to be monitored. A radiation transmitter and a radiation receiver are provided, which produce an angled course of the radiation because of reflection at the boundary surface. The radiant power of the receiver is indicated in an evaluating display element. In dependence on whether the boundary surface is wetted or not by the liquid, the fraction of the radiation which, on the one hand, is reflected to the receiver and, on the other hand, is refracted away from the receiver into the other medium, varies at the boundary surface.
